Streetfighter V4sp2 Issue

  1. Ok so took it to Ducati. They said 2 codes for the exhaust valves. So I removed the servo and installed the eliminator and the valve is in the open position. Now I have a different issue and the bike seems to have a limiter above 7000rpm it sounds like it is running on 2 cylinders over 7000 and revs out at 9000rpm.
     
  2. The servo eliminators don’t work I’m afraid.. you have to get a remap
     
  3. Would it give this issue? Why would it go from revving upto 6000rpm really slowly to now revving to 9000rpm and having a limiter.
     
  4. I’m thinking about putting an exhaust and map on it but only if that will fix this problem. There is no other fault codes showing
     
  5. Get it on a dyno and read some live data from it.

  6. Yes, that’s what mine has been doing. I didn’t realise for quite a while that the exhaust servo being missing was the cause..

    I would suggest a map from Duessen Engines in Germany. It’s a big upgrade.
     
  7. (And fixes the limp mode)
